Application filed June 8, 1899. Serial No. 719,801. No model.)

T at 1072 0711 it may concern: I

Be it known that I, GEORGE W. MANUEL, a citizen of the United States,residing in the city of Oakland, county of Alameda, State of California,have invented an Improvement in Window-Fasteners; and I hereby declarethe following to he a full, clear, and exact description of the same.

My invention relates to a device for fastening windows so as to makethem burglan proof and also to prevent rattling of loose sashes.

My invention consists in the construction and combination of partshereinafter described and claimed.

Figure 1 is a transverse section through the meeting-rails of the twosashes, showing the application of my device. Fig. 2 shows the sashesseparated and the engagingbolt and an inclined plate which retracts thebolt when the sashes are closed and makes it automatically engage withthe keeper. Fig. 3 is a perspective View of the bolt. Figs. 4 and 5 arefront and edge views, respectively, of the keeper-plate.

The object of my invention is to provide a latch and fastening forwindows which will i be invisible from the outside, which willautomat-ically engage and latch the sashes together whenever the windowsare closed, and which may be then turned so as to draw the sashestogether and lock them closely to prevent rattling and to form a burglar-proof fastening for the sashes or other equivalent parts to whichthe device may be applied.

A is a bolt which is slidable through a sleeve or socket B, the latterbeing fitted into a hole bored through the upper rail of the lower sashat some point between its ends. The bolt A is slidable longitudinally inthe sleeve 13 and made smaller at one point and surrounded within thesleeve by a spiral spring, as shown at O. This spring acts to normallypress the bolt forward and project it beyond the end of the sleeve B.The inner end of the bolt is fixed to or formed with a handle-piece D,by which it is turnable, for a purpose hereinafter described.

The outer end of the bolt A has upon it the radially-projecting lugs a,and these are adapted to enter a substantially oval hole E,

made in the keeper F, which is bolted or 0th erwise fastened to thelower rail of the upper sash in line with the bolt A. The upper part ofthis keeper has another upwardlyprojecting and curved plate G, which issunk into the edge of the upper-sash rail in line with the bolt A, whenthe sash-rails are separated by sliding one sash up or the other sashdown. The end of the bolt A pressed by the spring 0 will project beyondthe inner face of the lower-sash rail 1-1, and the curved plate G,carried by the upper-sash rail H,

will stand below the end of the bolt in line therewith, so that when thesashes are closed the end of the bolt striking the inclined face of theplate G will be temporarily pushed back into the notches A in the end ofthe socket B, whereby the bolt is held against accidental rotation andwith the lugs in proper position until the lugs a arrive in line withthe opening E of the keeper F. When this occurs, the spring G will forcethe bolt forward until the lugs are projected into the keeper, and inthis manner the sashes will be automatically lockedtogether wheneverthey are closed.

In order to draw the sashes together and to prevent rattling and to morefirmlysecure them, I have shown the keeper and periphery of the openingE of the beveled form with the inclined or cam-shaped surfaces I, sothat by turning the bolt A by means of the stem or handle D the lugs Ctwill be caused to move over this inclined orca in surface I and willthus act to draw the sashes firmly together and prevent any rattling ormotion.

It will be impossible for any one from the outside to obtain access tothe bolt or in any way tamper with it so as to open the windows. Whenthe window is to be opened, it is only necessary to turn the handle,bringing the lugs a of the bolt into line with the long diameter of theopening E, and to then withdraw the bolt into the socket B sufii cientlyto allowit to pass the keeper when the sashes are moved.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination with a spring-pressed bolt fitted to the rail of onesash and having lugs projecting radially from its outer end, of a andadapted to automatically retract the bolt keeper fitted to a rail of acompanion sash and guide its outer end to said opening. 10
